摘要
基于通用有限元分析软件ANSYS,采用有限元法对某自卸沙船总振动进行了仿真计算和分析预报;将有限元法计算结果与经验公式计算结果进行比较。此外,将船体总振动固有频率与主机及螺旋桨的固有频率对比分析,其结果证实目标船总振动固有频率储备满足《船上振动控制指南(2012)》要求。
By using the finite element analysis software ANSYS, the overall vibration of a self-unloading sand ship is simulated and analyzed and the calculation results are compared with the values calculated by empirical formula. After compared with the frequencies of the ship engine and propeller, the natural frequency of the self-unloading sand ship is proved to meet the requirements of the Guidelines for Shipboard Vibration Control（2012）.
